OBJECTIVE: We aimed to create a reproducible lung injury model utilizing injection of mitochondrial damage-associated molecular products. Our goal was to characterize the pathophysiologic response to damage-associated molecular pattern mediated organ injury. SUMMARY BACKGROUND DATA: There remain significant gaps in our understanding of acute respiratory distress syndrome, in part due to the lack of clinically applicable animal models of this disease. Animal models of noninfectious, tissue damage-induced lung injury are needed to understand the signals and responses associated with this injury...

The world is undergoing an unprecedented shift in demographics, with the number of individuals over the age of 60 projected to reach 2 billion or more by 2050, representing 22% of the global population. The elderly are at a higher risk for chronic disease and more susceptible to infection, due in part to age-related dysfunction of the immune system resulting from low-grade chronic inflammation known as "inflamm-aging". The innate immune system of older individuals exhibits a diminished ability to respond to microbial threats and clear infections, resulting in a greater occurrence of many infectious diseases in the elderly...

Extracorporeal membrane oxygenation (ECMO) is temporary life-support technology that provides time to rest the cardiac and respiratory system of critically ill people with acute, reversible medical conditions. Health care providers face emotional and challenging situations, where death may result, when withdrawing ECMO. A deepening of understanding of the ethical issues involved can aid clinicians in handling such difficult situations, leading to a possible mitigation of the moral problems. Toward this end, the ethical issues raised in the consideration of ECMO withdrawal are analyzed with respect to the ethical principles and concepts of autonomy, nonmaleficence/beneficence, medical futility, moral distress, and justice...

BACKGROUND: The optimal anticoagulation strategy for venovenous extracorporeal membrane oxygenation (VV-ECMO) is not known. OBJECTIVE: To evaluate the safety of anticoagulation strategies and monitoring during VV-ECMO for respiratory failure. DATA SOURCES: We conducted a systematic review to evaluate the association between anticoagulation strategies during VV-ECMO and pre-specified outcomes including major bleeding episodes, thrombotic events, and in-hospital mortality...

BACKGROUND: It is unclear whether an "obesity paradox" exists in the respiratory system, especially in acute respiratory distress syndrome (ARDS) and acute lung injury (ALI). Previous studies have postulated a causal relation between obesity and ARDS/ALI but have lacked power to form a definitive conclusion. OBJECTIVE: To investigate the relationships between obesity, ARDS/ALIrisk, and mortality. METHODS: A systematic search current to April 2016 was performed in Pubmed, EMBASE, Medline, Cochrane databases to find relevant studies...

Sepsis and the acute respiratory distress syndrome (ARDS) are major causes of mortality without targeted therapies. Although many experimental and clinical observations have implicated gut microbiota in the pathogenesis of these diseases, culture-based studies have failed to demonstrate translocation of bacteria to the lungs in critically ill patients. Here, we report culture-independent evidence that the lung microbiome is enriched with gut bacteria both in a murine model of sepsis and in humans with established ARDS...

RATIONALE: For acute respiratory distress syndrome (ARDS), mechanical ventilation (MV) is a life-saving intervention without alternative, however, MV can cause ventilator-induced lung injury (VILI). Reactive oxygen species (ROS) play important roles in the pathogenesis of both ARDS and VILI. Lecithinized superoxide dismutase (PC-SOD) has overcome limitations of SOD such as low tissue affinity and low stability in plasma. OBJECTIVES: In this study, we have examined the effect of PC-SOD on tissue injury, edema and inflammation in the lung and other organs of mice subjected to cecal ligation and puncture (CLP), lipopolysaccharide (LPS) administration or MV...

Critical care transport (CCT) teams are specialized transport services, comprised of highly trained paramedics, nurses, and occasionally respiratory therapists, offering an expanded scope of practice beyond advanced life support (ALS) emergency medical service teams. We report 4 cases of patients with severe acute respiratory distress syndrome from influenza in need of extracorporeal membrane oxygenation evaluation at a tertiary care center, transported by ground. Our medical center did not previously have a ground CCT service, and therefore, in these cases, a physician and/or a respiratory therapist was sent with the paramedic team...

OBJECTIVES: A recent individual patient data (IPD) meta-analysis suggested that patients with moderate or severe acute respiratory distress syndrome (ARDS) benefit from higher positive end-expiratory pressure (PEEP) ventilation strategies. However, thresholds for continuous variables (eg, hypoxaemia) are often arbitrary and linearity assumptions in regression approaches may not hold; the multivariable fractional polynomial interaction (MFPI) approach can address both problems. The objective of this study was to apply the MFPI approach to investigate interactions between four continuous patient baseline variables and higher versus lower PEEP on clinical outcomes...

Acute respiratory distress syndrome (ARDS) is a fulminant clinical disorder of varied etiology, characterized by diffuse lung injury and severe hypoxemia. It is a leading cause of ICU admission and the associated high mortality has sparked a lot of research on etiology, outcome, scoring systems, mortality predictors, biomarkers including inflammatory cytokines and even genomics in ARDS. The previously used AECC (American European Consensus Conference) definition (1994) of ARDS was replaced by the recent Berlin definition (2012) so as to improve its validity and reliability...

Acute respiratory distress syndrome (ARDS) is characterized by increased pulmonary inflammation and endothelial barrier permeability. Omentin has been shown to benefit obesity-related systemic vascular diseases; however, its effects on ARDS are unknown. In the present study, the level of circulating omentin in patients with ARDS was assessed to appraise its clinical significance in ARDS. Mice were subjected to systemic administration of adenoviral vector expressing omentin (Ad-omentin) and one-shot treatment of recombinant human omentin (rh-omentin) to examine omentin's effects on lipopolysaccharide (LPS)-induced ARDS...

Heated, humidified high-flow delivered by nasal cannulae (HHHFNC) is increasingly used for noninvasive respiratory support in preterm infants and critically ill children due to its perceived effectiveness and ease of use. Evidence from randomized controlled trials suggests that HHHFNC and continuous positive airway pressure (CPAP) are equally effective as postextubation support in preterm infants. HHHFNC is also used for weaning preterm infants from CPAP. Data on HHHFNC used as the primary support for treating respiratory distress syndrome are conflicting...

Adult onset Still's disease (AOSD) is a systemic inflammatory disorder characterized by rash, leukocytosis, fever and arthralgia/arthritis. The most common pulmonary manifestations associated with AOSD are pulmonary infiltrates and pleural effusion. The present study describes a 40-year-old male with AOSD who developed fever, sore throat and shortness of breath. Difficulty breathing promptly developed, and the patient was diagnosed with acute respiratory distress syndrome (ARDS). The patient did not respond to antibiotics, including imipenem, vancomycin, fluconazole, moxifloxacin, penicillin, doxycycline and meropenem, but was sensitive to glucocorticoid treatment, including methylprednisolone sodium succinate...

BACKGROUND: End-inspiratory pause (EIP) prolongation decreases dead space-to-tidal volume ratio (Vd/Vt) and PaCO2. We do not know the physiological benefits of this approach to improve respiratory system mechanics in acute respiratory distress syndrome (ARDS) patients when mild hypercapnia is of no concern. METHODS: The investigation was conducted in an intensive care unit of a university hospital, and 13 ARDS patients were included. The study was designed in three phases...
